You simply need to create a for loop that will skip the unneeded characters until you find "\r\n\r\n" substring.
It can be done with something like (untested):

Code: Select allchar *ptr = buffer;
int len = strlen(buffer);
for (int = 0; i < len; i++) {
    if (strncmp(ptr++, "\r\n\r\n", 4) == 0) break;
}
ptr += 3;
Serial.println(ptr);


Hmmmm, ok, i will test this.
Just another question, this i put between that 2 lines, correct?



Your code

Yes ! between the wifi.recv and the rest of the code.
But, as you can see, I've already printed the result with a single Serial.print(ptr), so no need to keep your "for loop" for printing, especially that printing one character at a time is pretty slow and useless...

Yes, that's is my problem. Can I change the library for ESP8266Wifi? https://github.com/esp8266/Arduino#installing-with-boards-manager

I don't understand how i change the Serial in this Library above for my case...

It is not clear what was your previous setup ...
Was it an Arduino connected with an ESP using AT firmware ?
The ESP8266WiFi is for an ESP stand-alone (without any Arduino).
